It's not like PS4 has done anything groundbreaking; what Sony did made sense. They evolved their product linearly. It's the next iteration of the PS3. It's just better, it's "next gen".

What? The last two times they made an expensive exotic machine that is hard to program for. This time they took a game-pc with standard x86 and a unified single 8GB memory. All this stuff is proven technology and easy to use and understand.
